The super sedan with around 600 horsepower goes all out at the Green Hell during final testing.
The Mercedes-AMG E63 S Sedan better watch out as BMW is currently putting the finishing touches on its next M5. Seen here is a near-production prototype flexing its V8 muscle at the Nordschleife ahead of what will be a full reveal in the months to come. As the lengthy video shows, the test driver was really pushing the car to its limits by tackling the 73 turns (33 left, 40 right) of the track at high speeds.
The new BMW M5 (F90) is expected to feature an upgraded version of the current biturbo 4.4-litre V8 engine delivering more than 600 horsepower. With the new 5 Series switching to the CLAR platform, it means the range-topping version of the lineup will also shed some weight to further boost performance and at the same time increase mpg numbers.
For the first time ever, the M5 will adopt an xDrive arrangement. That doesn’t mean the tail-happy RWD setup will be gone as reports are indicating BMW will install a system allowing drivers to simply choose which of the two axles is going to receive the engine’s power. As a side note, the aforementioned E63 S already has that in the shape of a Drift Mode.
For those who simply can’t wait for BMW to take the wraps off the M5, there are two alternatives available right now. The first would have to be the M550i xDrive quicker in the sprint to 60 miles per hour (96 kilometres per hour) than the old M5. The other one comes from Alpina and its recently introduced B5 Bi-Turbo. It’s also available in a Touring version, so it can act as a substitute for the M5 wagon BMW stubbornly won’t bring back.
If you can patiently wait, the new M5 will likely celebrate its world debut at the Frankfurt Motor Show in September. An online reveal might occur a few weeks earlier.
